  2. 6. Thymic studies. Investigations into the effects of childhood thymectomy, and characterization of thymic B cells and Hassall's corpuscles

    Author : Christina Lundqvist; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thymus; thymectomy; TCR; B cells; APC; Hassall s corpuscles; AIRE;

    Abstract : This thesis focuses on the human thymus, a primary lymphoid organ responsible for the maturation of T cells. Progenitors arrive from the bone marrow and start to randomly assemble their T cell receptor (TCR) followed by a thorough selection process in which the TCR is tested for functionality and autoreactivity.

  4. 7. Characteristics and functions of thymic exosomes in human and mouse

    Author : Gabriel Skogberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exosome; thymus; tissue-restricted antigen; Aire; Down syndrome;

    Abstract : Thymocytes develop in the thymus to become a functional pool of T-cells in the periphery. To achieve this, the thymocytes go through several steps of maturation and selection within the thymus. READ MORE

  5. 8. Adseverin – An Immune-Specific Target of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin

    Author : Camilla Svensson; Lars Wärngård; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; 2; 3; 7; 8-Tetrachlorodibenzo-p-dioxin; TCDD; adseverin; aryl hydrocarbon receptor; immunotoxicity; thymus; cytoskeleton; Toxikologi; Toxicology; Toxikologi; Toxicology; toxikologi;

    Abstract : The environmental pollutant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induces thymus atrophy and immunosuppression in all animal species examined and these effects constitute a potential risk to humans. TCDD can via binding to the intracellular aryl hydrocarbon receptor (AhR), modulate transcription of a number of genes and the aim of this thesis has been to identify such genes, which may explain the mechanisms behind TCDD-mediated immunotoxicity.

  6. 9. Early childhood thymectomy - impact on immune function

    Author : Judith Gudmundsdottir; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Immunologi; Thymus; Pediatric cardiac surgery; Congenital heart defect;

    Abstract : Introduction: The thymus is the site of T cell maturation. Children born with a congenital heart defect often endure surgery early in life, and during surgery their thymus is routinely removed, as it blocks the surgeons access to the heart. READ MORE

  7. 10. Thymic Stroma and T Cell Development. Impacts of Retinoic Acid Signaling

    Author : Kerstin Wendland; Slemhinnans immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thymus; Thymic epithelial cells; Retinoic acid; T cell development; Stromal Cells;

    Abstract : The development of functionally competent, self-tolerant T cells in the thymus is an essential prerequisite for the formation of adaptive immune responses against foreign pathogens. Thymic epithelial cells (TECs) form specialized stromal microenvironments in the cortex (cTEC) and medulla (mTEC) of the thymus that support all stages of T cell development, from the entry of thymocyte progenitors to the exit of mature naive T cells.
